j Another object of the invention is to provide a device of the above described character,

'which is adaptedto'firnily secure the paper sheetstogether and hold them in such condition While a binding cement is applied to the A furth'er objector the invention is to provide a structurefo'r .thepurpose above described, which is'of simple but s'trong and durablecons'truction and easy to operate;

V The invention will be best understood-from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this speci- 2 fication, with the understandingyhowever,

that the invention is'not confined to any strict conformity with the showing of the'drawings 7 but may be changed'or modified so long as such changes or modifications mark no mate 3 0 rialdeparture.fromjthexsalient features of the invention as expressed in" the appended claims. 1 L j g In the drawings;

The upper end of the brace lO'which v is hooked or curvedto engage'in the'a'pen tured bracketplate 9,,is indicatedby' the v 'numeral 11;. 'f Each sidewall 2 has formed therethrough,

Edirectly beneaththe top 5, an opening 12 and a flange 13 extends inwardly from each side wall at the bottom of eachopening as vshown in Figures 1' and-3. Each' ofthese 'openings512 has mounted therein a'bearing block 14, one edge of "which is 1 beveled slightly, as shown, and has positioned thereagainst a wedge block 15. In actual practice the'inclined contacting surfaces; between the bearing blocks 14;, and thewedge blocks. 15

t are very slight so that the wedges 15 maybe shifted frombelow the bearing blocks let to the top thereofin order to shift-the bearing blocks as desired and without making it necessary to turn the bearing blocks over. The inclination of the contacting beveled faces 1 of the bearing and wedge blocks, as shown in the drawings, is greatlyexagg'erated order toclearly bring out the fact thatthere does exist a slight bevelupon these surfaces; 1 I i V The; bearing'blocks' 14 have extended thereo through the eccentrically"positioned trunnions 16 which are carried by the press bars or eccentrics 17.

These eccentric press bars extend from one bearing block to the other through the top of the cabinet, in the manner shown, and their rotation is facilitated by the hand wheels 18 mounted upon the outer ends of the trunnions 16.

The cabinet is provided with spacing blocks 19 at the sides thereof whiclrmay be employedto support and hold in spaced re lation the false bottoms 20. It will of course be seen, asthe description of the operation of the device is given, that these false bot toms 20 may be removed if the stack of sheets 21 is of such a height that it will fill the interior of the cabinet. If there is only a small stack of sheets to be pressed then the false bottoms 20 may be mounted in position, in the manner shown, between the. spacing blocks 19 so as to bring the top of the stack into close proximity to the eccentric press bars17. V

When a stack of papers is placed inthe press, as shown in Figures l and 3, the press bars 17 are turned so that they will be raised above the center of rotation of the trunnions and, at the same time, the wedge blocks l'5 are inserted between the lower edges of the bearing blocks and the flanges 13 at the bottomsof the openings 12. After the stack of paper sheets has been placed in position there is placed thereon a press board 22, and the wedge blocks are then shifted from the bottom to the top of the bearing blocks as shown in Figure 3. It will be seen that upon then rotating the hand wheels 18 the eccenof or upon the main bottom, the cabinet will be supported in the inclined position shown in Figure 6 by the supporting leg 10 and the inner edges of the sheets will thus be positionedagainst the door which forms a portion of the back wall of the cabinet. After the sheets or papers h'a-vebeen compressed in the manner described, the cabinet is set upright and the door 7 removed thus exposing the inner edges of the sheets so that a suitable glue or cement may be applied thereto. After the application of the glue or cement .the same is allowed to dry'before removing the pressure exerted upon the sheets by the eccentric bars 17, after which the stack of sheets may be removed and divided into pads of suitable thickness to which backs may then be applied.
